> Kafka Streams allows to pass in different configs for different clients by prefixing the corresponding parameter with `producer.` or `consumer.`.
> However, Kafka Streams internally uses multiple consumers, (1) the main consumer (2) the restore consumer and (3) the global consumer (that is a restore consumer as well atm).
> For some use cases, it's required to set different configs for different consumers. Thus, we should add two new prefix for restore and global consumer. We might also consider to extend `KafkaClientSupplier` and add a `getGlobalConsumer()` method.
